ELECTRIC HAIR-CLIPMNC MACHINE. f'

SPECIFICATION forming para of meters Patent No. 532,188, dated January 3,1895.

Application ined April 27, 1ee4'.

To all whom t may concern/.q

Beit known that I, PETER SHANNON, a citizen of the United States, residing at Chicago,- 1n the county of Cook andV State of Illinois, have invented certain newanduseful Improvements 'in Electric Hair-Clipping Machiues; and I do hereby declare the followingl to be aV full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part' of this specification.

This invention relates to that class ot' hair clipping machin es, in which the vibratingcutter plate or bar of the machine has connection with and is propelled by the revolving armature shaft of an electric motor.

The Objects of the present improvement are as follows: to provide an improved construction and arrangement of the cutting, and electric impelling mechanisms, whereby a ready and convenient attachment and detach- `ment of the electric motor proper can be effected; a convenient and efficient housing or inclosing of the electric motor parts against access of dust, dying particles of hair, dac.; a simple and accurate means of adjustment, for the cutter plates, with relation to each other to compensate for wear; and a durable and eective connecting mechanism between the armature shaft and the vibrating cutter plate, by which the proper vibration or reciprocation is imparted yto such cutter plate in the operation of the machine. I attain such objects by the construction and arrangement of parts illustrated in the accompanying drawings, in which- Figure 1, is a vertical sectional elevation of an electrical hair clipping machine, constructed in accordance with my present invention; Fig. 2, a horizontal section ofthe same at line m-, Fig. 1, with parts broken away; Fig. 3, an enlarged detail sectional'elevation; illustrating the construction of the pivot for the vibrating cutterplate; Fig. 4, a detail horizontal section of the same at line .af-m', Fig. 3; Fig. 5, a similar view at line t2- m2, Fig. 3.

Similar numerals of reference indicate like parts in the several views.

Referring to the drawings 1, represents the stationary cutter plate, having the usual cutting serrations or teeth 2, at its forward edge,

'serial No.`5o9,242. .i (No modell) l 4 and `which extends backward to carry the pivot stud of the vibrating cutterplate, as well'as the inclosing housing ot' the electric motor mechanism. j

3, is the vibrating cutter plate having the usual cutting serrations or teeth 4, at its forward edge, and which in the operation of the machineV move across the teeth of the stationary plate l, to eiectla severing or clipping of. the hair.

5, is ay rearwardly extending bar orlever xedly secured at front tothe vibrating cutter plate, as shown, and midway of its length provided with a pivot neck 6, fitting the pivot stud 7, that is xedly attached to the stationary plate 1 lAtits rear end the bar or lever 5 is provided with' a'l longitudinally Aslotted yoke 5', in which slides the block 8, inwhich is journaled the crank pin 9, on the lower end of the shaft l0, of the armature of the electricmotor 11, f

12, is an upwardly extending neck on the rear portion of the mai-n plate 1, slotted at front for. the passage of the bar or lever 5, and forming an inclosing housing for the yoke portion 5 of such lever, and the sliding block S and operating crank on the motor armature.

The electric motor 11, is inclosed Within a casing 13, having a removable lid 14, and a horizontally extending handle 15, by which the operator manipulates the machine. yThe lower end of the casing 13, is formed with a pivot collar 16, that has pivotal bearing on the neck 12, of the stationary cutter plate or base, between the lower fixed collar 17,and the upper annular nut 18, screwing upon the upper Vend of the neck l2, as clearly illustrated in Fig. 1. This improved construction admits of the casing and holdinghandle being swung around in a horizontal plane so that the handle can be placed in a desired can bel conveniently manipulated by the operator.

ICO

In the present improvement the lower bear ing of the lever or bar 5, is upon a collar 22, supported by a nut 23, screwing upon the lower screw threaded portion of the pivot shank or stud, such collar being'made nonrotary by a lip 24, sliding in a vertical groove 25, in the shank '7, so that such collar will take up the turning strain of the lever 5 in its vibrations, and prevent any transmission of the same to the nut 23, with the accompanying tendency of the same to unscrew away from its adjustment.

The lever or bar 5, is held in place by a temper nut 26, and an interposed collar 27, that is made non-rotary by a lip 28, sliding 1n a vertical groove 29, in the upper screw threaded extension 30, of the pivot shank as shown. The purpose of this non-rotary collar is similar to that of the collar 22, to prevent the turning movement of the lever 5, being imparted to the temper screw, and affect the desired tension adjustment of the same.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an electrical hair clipping machine,the combination with the stationary and vibrating clipper plates, of a lever 5, secured to the Vibrating clipper plate, and having a slotted yoke at its rear end, a sliding block 8, moving in said yoke, an electric motor supported on a rearward extension of the stationary cutter plate, the armature thereof carrying a crank pin engaging the sliding block 8, and aninclosing casing attached to rearward extension of the stationary cutter plate, and supporting the electric motor in a plane at right angles to such cutter plate, substantially as set forth.

2. In an electric hair clipping machine, the

combination with the stationary and vibrating clipper plates and an electric motor for operating the same, of a casing secured in a horizontally adjustable manner to the stationary cutter plate, and forming an inclosin g and supporting means for the electric motor, substantially as set forth.

8. In an electric hair clipping machine, the combination with the stationary and vibrating clipper plate, and an electric motor for operating the same, of a casing secured in a horizontally adjustable manner to the stationary cutter plate, and forming an inclosing and supporting motor, and a spring dog for locking the same at the required adjustment, substantially as set forth.

4. In an electric hair clipping machine the combination with the stationary and vibrating clipper-plate, and an electric motor for operating the same, of a casing secured in a horizontally adjustable manner to an upwardly extending neck on the main plate 1 by collar 1'7, and annular nut 18, substantially as set forth.

5. In an electric hair clipping machine, the combination with the stationary and vibrating clipper plates, and an electric motor for operating the same, of a casing secured in a horizontally adjustable manner to an upwardly extending neck on the main plate 1 by collar 17, and annular nut 18, formed with peripheral notches 19, and a spring'bolt 20, engaging notches, substantially as set forth.

In testimony whereof witness my hand this 11th day of April, 1894.

PETER SHANNON.
